The trumpeter swan was once eradicated from Minnesota

During the Nineteenth Century, the trumpeter swan was so over-hunted for food and the fur trade that it completely disappeared from Minnesota, according to a press release from the state. According to Audubon.com, there were fewer then 100 trumpeter swans south of Canada by the 1930s.

However, thanks to protection from hunting and other conservations efforts including reintroducing the species to its breeding range across the northwest of North America, the swans are listed as Least Concern on the Red List and have even returned to Minnesota with numbers as high as 17,000.
